What is a Simple Machine?
Have you ever used a see-saw, a slide, or a wheelbarrow?
Then you have already used a simple machine!
A simple machine is a tool that helps you push, pull, or lift
things with less effort. It makes hard work easier!
There are 6 types of simple machines — and they
are everywhere around you! Let's meet them all. ⚙️✨
The Lever — Push & Lift!
A lever is a long bar that rests on a point in the middle. When you
push one end down, the other end goes up! 🎢
🎪 A see-saw in the playground is a lever!
✂️ Scissors are two levers working together!
🥄 Even a spoon can be a lever when you use it to open a lid!

called an axle. Together they make things roll! 🎡

A ramp is a flat surface that goes up at an angle. Instead of
lifting something straight up, you can push it
along the ramp — and it's much easier!

pull the rope down, the thing on the other end goes
up! It's like magic! 🪄

The Screw — Twist & Hold!
A screw is like a ramp wrapped around a stick!
When you turn a screw, it digs in and holds things together
really tight! 🔧
🪑 Screws hold your chair and table together!
🫙 A jar lid is a screw — you twist it to open and close!

on the other. You push the thin end into something and
it splits it apart! 💥

your food!
